Not that I know of.  But I even don't know a major mode which uses
optional arguments.  Maybe you confuse minor and major modes?

Calling the `foo-mode' function of one of the former usually toggle the
foo minor mode, and an optional argument is used to enable/disable it
explicitly.  But you cannot disable a major mode except by activating
another major mode, so there's no need for such an argument.
